"Ever since I created the first version of this video a year ago I've been wanting to try it again with more water and better lighting / footage. This is a really fun project and when you first see the results, chances are your jaw will drop. 
The main thing to keep in mind for this project is that you need a camera that shoots 24 fps."

The effect that you are seeing can't be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye. For that project, you'd have to use a strobe light.

For this project you'll need:
  1. A powered speaker
  2. Water source
  3. Soft rubber hose
  4. Tone generating software
  5. 24 fps camera
  6. Tape.
Run the rubber hose down past the speaker so that the hose touches the speaker. Leave about 1 or 2 inches of the hose hanging past the bottom of the speaker. Secure the hose to the speaker with tape or whatever works best for you. The goal is to make sure the hose is touching the actual speaker so that when the speaker produces sound (vibrates) it will vibrate the hose.

Set up your camera and switch it to 24 fps. The higher the shutter speed the better the results. But also keep in the mind that the higher your shutter speed, the more light you need. Run an audio cable from your computer to the speaker. Set your tone generating software to 24hz and hit play.Turn on the water. Now look through the camera and watch the magic begin. If you want the water to look like it's moving backward set the
frequency to 23hz. If you want to look like it's moving forward in slow motion set it to 25hz.

Have fun!

It's not levitation, (if you look half way though the video above), you can see the hose is vibrating ever so slightly, resulting in the water coming out in a wave pattern too fast fro the eye to comprehend. Kind of like how a wheel appears to stop turning or turn backwards at high speeds.
